short - horned lizard (P. douglassii)
Did you know that "Horny Toads" are not toads at all? There are from the lizard family. When theatened by a predator, some horny toads can squirt blood from a gland on each lower eyelid. The stream can reach up to 4 feet and is distasteful to canines. Their head spikes can prove fatal to snakes that try to swollow a horned lizard.
This little guy was nice enough to let me take a shot of him.
